Abstract:

Based on the GIS technology and remote sensing images of 2005 and 2010, the special characteristics of landuse change were revealed for the section of the Liao River. The authors analyzed the fundamental drivingforce factors of landuse change and set up a multiple linear regression equation using the principle component analysis based on the software of SPSS and the socialeconomy statistical data. As a result, the demographic factor, socioeconomic factor, levels of industrialization and urbanization and agricultural development factor were the main factors affecting the landuse change for the Jilin section of the Liaohe River, which provided the basis and the reference for economic development of survey region.

Key words: landuse change, geographic information system (GIS); principle component analysis, drivingforce factor
